Regulierung internationaler Finanzmärkte und Banken

Diese Forschungsgruppe analysiert Ursachen und Konsequenzen von internationalen Aktivitäten von Banken sowie den regulatorischen Rahmen, innerhalb dessen globale Banken operieren.

International aktive Banken können eine effiziente internationale Kapitalallokation vereinfachen und zur internationalen Risikoteilung beitragen. Allerdings können sie auch Instabilitäten generieren und zu einer Übertragung von Schocks über nationale Grenzen hinaus beitragen. Dies ist einer der Gründe für die aktuelle Re-Regulierung des internationalen Bankensystems.

Die Forschungsgruppe trägt auf drei verschiedenen Wegen zur Literatur bei. Erstens analysiert die Gruppe empirisch, warum internationale Banken global aktiv sind und wie Schocks im Finanzsystem übertragen werden. Zweitens untersucht die Gruppe das Entstehen von systemischen Risiken und Ungleichgewichten im integrierten Bankenmarkt und die sich daraus ergebenden Konsequenzen für die Realwirtschaft. Drittens werden die Auswirkungen von Änderungen bezüglich der Bankenaufsicht und Bankenregulierung analysiert, mit einem besonderen Fokus auf dem europäischen Integrationsprozess

Financial Incentives and Loan Officer Behavior: Multitasking and Allocation of Effort under an Incomplete Contract

P. Behr A. H. Drexler Reint E. Gropp Andre Guettler

in: Journal of Financial and Quantitative Analysis, im Erscheinen

Abstract

We investigate the implications of providing loan officers with a nonlinear compensation structure that rewards loan volume and penalizes poor performance. Using a unique data set provided by a large international commercial bank, we examine the main activities that loan officers perform: loan prospecting, screening, and monitoring. We find that when loan officers are at risk of losing their bonuses, they increase prospecting and monitoring. We further show that loan officers adjust their behavior more toward the end of the month when bonus payments are approaching. These effects are more pronounced for loan officers with longer tenures at the bank.

Foreign Ownership, Bank Information Environments, and the International Mobility of Corporate Governance

Yiwei Fang Iftekhar Hasan Woon Sau Leung Qingwei Wang

in: Journal of International Business Studies, im Erscheinen

Abstract

This paper investigates how foreign ownership shapes bank information environments. Using a sample of listed banks from 60 countries over 1997–2012, we show that foreign ownership is significantly associated with greater (lower) informativeness (synchronicity) in bank stock prices. We also find that stock returns of foreign-owned banks reflect more information about future earnings. In addition, the positive association between price informativeness and foreign ownership is stronger for foreign-owned banks in countries with stronger governance, stronger banking supervision, and lower monitoring costs. Overall, our evidence suggests that foreign ownership reduces bank opacity by exporting governance, yielding important implications for regulators and governments.

Cross-border Transmission of Emergency Liquidity

Thomas Kick Michael Koetter Manuela Storz

in: Journal of Banking & Finance, im Erscheinen

Abstract

We show that emergency liquidity provision by the Federal Reserve transmitted to non-U.S. banking markets. Based on manually collected holding company structures, we identify banks in Germany with access to U.S. facilities. Using detailed interest rate data reported to the German central bank, we compare lending and borrowing rates of banks with and without such access. U.S. liquidity shocks cause a significant decrease in the short-term funding costs of the average German bank with access. This reduction is mitigated for banks with more vulnerable balance sheets prior to the inception of emergency liquidity. We also find a significant pass-through in terms of lower corporate credit rates charged for banks with the lowest pre-crisis leverage, US-dollar funding needs, and liquidity buffers. Spillover effects from U.S. emergency liquidity provision are generally confined to short-term rates.

Lending Effects of the ECB’s Asset Purchases

Michael Koetter

in: Journal of Monetary Economics, im Erscheinen

Abstract

Between 2010 and 2012, the European Central Bank absorbed €218 billion worth of government securities from five EMU countries under the Securities Markets Programme (SMP). Detailed security holdings data at the bank level affirms an effective lending stimulus due to the SMP. Exposed banks contract household lending, but increase commercial lending substantially. Holding non-SMP securities from stressed EMU countries amplifies the commercial lending response. The SMP also improved liquidity buffers and profitability without compromising credit quality.

Asymmetric Investment Responses to Firm-specific Forecast Errors

Julian Berner Manuel Buchholz Lena Tonzer

in: IWH-Diskussionspapiere, Nr. 5, 2020

Abstract

This paper analyses how firm-specific forecast errors derived from survey data of German manufacturing firms over 2007–2011 affect firms’ investment propensity. Understanding how forecast errors affect firm investment behaviour is key to mitigate economic downturns during and after crisis periods in which forecast errors tend to increase. Our findings reveal a negative impact of absolute forecast errors on investment. Strikingly, asymmetries arise depending on the size and direction of the forecast error. The investment propensity declines if the realised situation is worse than expected. However, firms do not adjust investment if the realised situation is better than expected suggesting that the uncertainty component of the forecast error counteracts positive effects of unexpectedly favorable business conditions. Given that the fraction of firms making positive forecast errors is higher after the peak of the recent financial crisis, this mechanism can be one explanation behind staggered economic growth and slow recovery following crises.

Financial Linkages and Sectoral Business Cycle Synchronisation: Evidence from Europe

Hannes Böhm Julia Schaumburg Lena Tonzer

in: IWH-Diskussionspapiere, Nr. 2, 2020

Abstract

We analyse whether financial integration between countries leads to converging or diverging business cycles using a dynamic spatial model. Our model allows for contemporaneous spillovers of shocks to GDP growth between countries that are financially integrated and delivers a scalar measure of the spillover intensity at each point in time. For a financial network of ten European countries from 1996-2017, we find that the spillover effects are positive on average but much larger during periods of financial stress, pointing towards stronger business cycle synchronisation. Dismantling GDP growth into value added growth of ten major industries, we observe that some sectors are strongly affected by positive spillovers (wholesale & retail trade, industrial production), others only to a weaker degree (agriculture, construction, finance), while more nationally influenced industries show no evidence for significant spillover effects (public administration, arts & entertainment, real estate).

Interactions between Bank Levies and Corporate Taxes: How is the Bank Leverage Affected?

F. Bremus Kirsten Schmidt Lena Tonzer

in: ESRB Working Paper Series, Nr. 103, 2019

Abstract

Regulatory bank levies set incentives for banks to reduce leverage. At the same time, corporate income taxation makes funding through debt more attractive. In this paper, we explore how regulatory levies affect bank capital structure, depending on corporate income taxation. Based on bank balance sheet data from 2006 to 2014 for a panel of EU-banks, our analysis yields three main results: The introduction of bank levies leads to lower leverage as liabilities become more expensive. This effect is weaker the more elevated corporate income taxes are. In countries charging very high corporate income taxes, the incentives of bank levies to reduce leverage turn ineffective. Thus, bank levies can counteract the debt bias of taxation only partially.

Do Conventional Monetary Policy Instruments Matter in Unconventional Times?

Manuel Buchholz Kirsten Schmidt Lena Tonzer

in: Deutsche Bundesbank Discussion Paper, Nr. 27, 2019

Abstract

This paper investigates how declines in the deposit facility rate set by the ECB affect euro area banks’ incentives to hold reserves at the central bank. We find that, in the face of lower deposit rates, banks with a more interest-sensitive business model are more likely to reduce reserve holdings and allocate freed-up liquidity to loans. The result is driven by well-capitalized banks in the non-GIIPS countries of the euro area. This reveals that conventional monetary policy instruments have limited effects in restoring monetary policy transmission during times of crisis.
